Allocate your take-home using the 1/3 rule: a third for today, a third for medium-term goals, a third for long-term security (insurance + investments). Auto-computes CPF and Singapore income tax.
A balanced allocation framework: a third of your take-home pay goes to Short-term Needs (daily living and lifestyle), a third to Medium-term Goals (2–5 year sinking funds like renovation, car, wedding, travel), and a third to Long-term Security — split roughly 12% on insurance protection and 21% on savings and investments.
The 50/30/20 rule lumps savings into a single 20% bucket and treats insurance as just another expense. The 1/3 rule weights today, tomorrow, and the long-run more evenly, and it makes insurance explicit (12%) rather than burying it in 'needs'. For most Singapore households building wealth and protecting against catastrophic risk simultaneously, the 1/3 framework is closer to a CFP-style plan.
Short-term Needs: rent or mortgage, utilities, groceries, transport, family support, dining, entertainment, shopping, subscriptions. Medium-term Goals: house renovation fund, car/COE fund, wedding fund, holiday fund, major-purchase fund — money you're setting aside monthly for spends 2–5 years out. Long-term Security: insurance premiums (term, CI, disability, hospital) plus emergency fund top-up, investments via DCA, SRS, and CPF voluntary top-ups.
That's the most common mismatch — high rent or aggressive lifestyle spending crowding out the other two thirds. Two levers: trim fixed costs (housing, transport) where possible, and timebox lifestyle line items like dining and shopping with monthly caps. Even a 5-point shift back into the long-term bucket compounds meaningfully over decades.
The calculator counts only your voluntary top-ups (RSTU, MA, SRS) and cash investments in the long-term bucket, since mandatory CPF is already auto-deducted from gross before take-home. Mandatory CPF is real wealth, but it's not a discretionary allocation — and the 1/3 rule is about how you direct the cash that hits your bank account.
It applies the 20% employee CPF rate capped at the Ordinary Wage ceiling of S$8,000/month (from 1 Jan 2026). It doesn't model the Additional Wage ceiling on bonuses or the age-based rate steps from 55 onwards — use the Salary calculator for the full picture.
Yes. It estimates annual income tax using the current resident rates (unchanged YA2024 - YA2026), deducts CPF and the $1,000 earned income relief plus any other reliefs you declare, and converts to a monthly figure to compute take-home pay.
A simple split of take-home pay: 50% to needs (housing, food, transport, bills), 30% to wants (dining, shopping, travel), and 20% to savings and debt repayment. It's easier to start with than the 1/3 rule, but it bundles insurance into 'needs' and savings into one 20% bucket. Use whichever you'll stick to.
It's a useful starting point, but high housing or childcare costs can push needs above 50% for many households, while frugal savers comfortably beat 20%. Treat the percentages as targets to adjust, not hard limits — the goal is a needs figure under control and a healthy, automatic savings rate.
Take-home (net) pay — what actually lands in your bank after CPF and tax. Both the 1/3 rule and 50/30/20 are applied to take-home, which is what this calculator does after estimating your CPF and income tax.
